Is it OK to delete all app cache data?
I want to clear all app cache data (App Cache) on my Android smartphone. I don't have rooted phone. So, I am not able to delete .apk files or .obb files.
Is it safe to delete all cache data (including .apk files and .obb files) on my phone?
It is safe to delete all cache data from your phone, because nothing will be lost from your SD card. You will not be able to restore the data you deleted, but this should not be a problem since you don't need those files anymore.
It is also safe to delete all apps cache data. You should be able to delete them, even if they are pre-installed on the phone. You can either delete the .apk files in the /system/app folder, or delete the .obb files in the /data/app folder.
